HERMAN FBO MM, .OF EAST NEW YORK, N. Y.

Letters Patent No. 65,370, dated June 4, 1867.

IMPROVED PRPELLER.

AIO ALL WHOM IT MAY CONCERN:

Bo it known that I, HERMAN FROMM, ot East New York, in the county of Kings, and State of New York, have invented a new and useful Improvement in Ii'epelling Vessels; and Ido hcrehy declare the following to he a full, clear, and exact description of the nature thereof, sufficient to enable others skilled in the art to which it appel-talus to fully understand'and use the same, reference being had to the accompanying drawings, 'making part ot' this specification, in which- Figure 1 is a side view of a vessel with my improvement attached, parts being broken away to show the construction.

Figure 2 is a detail view of the same. Y

My invention has for its object to furnish an improved and economical means for propelling vessels throughl the water; and it consists in driving the propeller-shaft by a wind-wheel, and in the combination of 'a horsepower with the shaft of the propeller-screw, substantially as hereinafter more fully described.

A is the hull of the vessel,- and B is mast, to the head et' which is securely attached a cap, e, the top .of which is a flat plate. yD is a flat circular' plate fitting upon the top of the cap c, to which it is pivcted hy the short vertical rod E, which passes through it, and has a bevel gear-wheel, V, attached to its upper end, the teeth of which mesh into the teeth ofthe bevel geanwheel F attached to the windwvheel shaft G, which revolves in hearings attached te the upperside of the said dish D. To 'one end of the shaft G is attached an ordinary wind-wheel, II, as shown in ligs. 1 and 2. To the side'of the disk D is attached a vane, I, to keep the wheel H always towards the wind. To the sha-ft E is attached a gear-wheel, J, the teeth of which mesh into the teeth ot' the gear-wheel K attached to the vertical shaft. The upper end oi' the shaft revolves in hearings in the cap e, and to its lower end is attached a bevel gear-wheel, M, the teeth of which mesh into the teeth of the bevel gcar-wheel W' attached to the shaft O, the rear end of which projects through the stern of the vessel and has a propeller-screw, I), attached to it, as shown in iig.1, so that the revolution of the wind-wheel II imparts motion to the screw I and propels the vessel. It is an ordinary horse-power, to the projecting end cf the shaft of which is attached a pulley, S, which is connected to the propeller-shaft O by a band, T, passing around it and around the pulley UA attached to the said shaft O, so that in case of the absence oi' wind the propeller-screw may he operated hy horse-power.

Having thus described my invention, what I claim as ncegand desire te secure by Letters Patent, is-

The combination of a windmill and an ordinary horse-power with the screw-shaft of a vessel, substantially as described for the purpose specified.

To the above I have signed my name this 17th day of April, 1867.
